SPECIFICATION forming part of Letters Patent No. 433,37'3, dated July 29,1890.

i Application filed September 27, 1889. Serial No. 325.325. (No model.)

i .To all whom, it may concern:

Be it known that I, FRANK SCHULZ,.a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows; and it has for its object `to provide a plow for general use whiclishall be simple, durable, and etlicient, and which maybe easily operated without danger of running unevenly or turning over.

lVith these ends in view the invention consists in the improved construction of the plow and of the draft attachment for the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of my improved plow and draft attachment. Fig. 2 is a side view of the same, taken from the opposite side. Fig. 3 is a rear view of the plow. Fig. 4 is a front elevation of the plo w provided with the draft attachment.

Like numerals of reference designate like parts in the several iigures.

The plow-beam 1, which is of ordinary construction, is provided with the downwardlyextending standard 2, to which the share 3 and mold-board 4 are attached. The standard has a rearwardly-extending heel-piece 5, to which are attached the lower ends of the handles G 6, the upper ends of which are secured to the beam and to the transverse brace or rung 7. Braces 8 are used to connect the handles with each other and with the moldboard, and a hook-bolt 9 connects one of said braces with the heel-piece 5. The landside 10, which is secured to the opposite side of the standard and to the heel-piece 5, extends below the latter, with which it forms an angular recess 12, in. which is secured an angular wear-plate 13, which is held detachably by means of bolts, so that when worn it may be readily removed and a new one substituted.

A colter 14, of ordinary construction, is secured detachably to one side of the beam directly in front of the mold-board.

The draft attachment comprises a wheeled frame, the axle of which 15 is mounted upon the furrow-wheel 1 6 andlandsidewheel 17, the

former of which is the larger, in order to cause the attachment to run evenly during' operation. The axle is provided with a horizontal slot 1S, in which the draft-bar or tongue 19 is transversely adjustable by means of a bolt 20, upon which it is pivotally mounted, and which may be adjusted in any one of a series of vertical perforations 2l, formed in the axle for its reception. A forwardly extending horizontal segmental bracket 22, the ends of which are secured to the axle, is provided with a series of perforations 23 to receive a bolt 24, extending through a slot 25 in the draft-bar, and having a thumb-nut 2G at its upper end to enable the direction ofthe draft to be adjusted by simply changing the bolt 24 from one to another of the perforations 23.

A pair of uprights 27, rising vertically from the axle near its ends, are connected at their upper ends by a transverse bar or brace 28, upon which is secured a block 29, having a vertical perforation 30, in which the upper end of a long screw-threaded rod 31 is swiveled by means of a set-screw 32, extending through the block 29, and the point of which enters an annular groove 33 in the said rod.

Upon the `upper side of the axle and sepa-` rated from it by blocks or washers 34 is mounted a bar or brace 35,having a series of perforations 36, in any one of which the lower end of the screw-threaded rod 3l maybe journaled, the block 29, in which the upper end of said rod is swiveled, heilig laterally adjustable upon the top bar 2S by means of a setscrew, in order to admit of the lateral adjustment of the screw-threaded rod in the manner described.

8S designates a clip havingfemale threaded eyes, by means of which it is ladj usted upon the screw-threaded rod 3l. The upper end of said clip has a laterally-extending offset or recess 39, in whichis fitted alink 40, to which is connected another link 41, through the outer end of which extends a set-screw 42,

bearing against a clevis 43, the body of which passes through the said link 41.

Mounted upon the screw-threaded rod 3l, above the clevis or clip 38, is a nut 44, having longitudinal arms 45, the outer ends of which are provided with notches 46.

The front end of the draft-bar or tongue 19 IOO is provided with a hook 47 for the attachment of the draft, and the rear end of said draftbar is connected by a chain 48 with a clevis 49, attached to the plow-beam directly in front of the colter.

For the purpose of connecting the wheel attachment with the plow-beam the latter is provided near its front end on one side with brackets 50, having perforations to receive Va bolt 5l, by means of which the clevis 43 may be attached to the plow-beam, as shown. The other side of the plow-beam'is provided with eyes 52,havinglinks 53,which may be hooked in the notches 4G at the outer ends of the arms 45, extending from the nut 44. The setscrew 42 may then be tightened, thereby connecting the plow-beam to the carrying-f rame with any desired degree of rigidity.

The operation and` advantages of my invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. The carrying-frame supports the front end of the beam, which .may be adjusted vertically by turning the screw-threaded rod 3l, the upper end of which is provided with a crank or handle 54, bymeans of which it may be easily manipulated. The distance to which the plow shall be permitted to enter the ground may thus be regulated. The direction of the draft may be adjusted by properly7 adjusting the tongue or draft-bar in the manner described, and it will be observed that access to the bolt 20, by which the draft-bar is transversely adjustable, may be had through several of the perforations 3G in the bar or brace 35 above the axle. One of the wheels of the supporting-frame runs in the furrow and the other on the land, and owing to the difference in size between the wheels an upright and vertical position will normally be maintained vby the frame during operation.

Adjustment may easily and quickly be made by the screwBl to cause 4the plow to ymake a furrow of any desired depth, and the supporting-frame may be readily applied to or detached from the plow. It is also capable of being used in connection with any plow of ordinary construction. Having thus described my invention,l claim and desire to secure by Letters Patent of the extending through the horizontal slot in the; laxle and secured adj ustably therein-bya bolt,

a bolt and a thumb-nut connecting the front end of the draft-bar adjustably with the segmental bracket, a frame mounted vertically upon the axle, a screw-threaded rod journaled in said frame, a clip mounted adj ustably upon said screw-threaded rod, means for connecting said clip with the front end of the plovv-beam, and a clevis and chain connecting the latter with the rear end of the draft-bar, substantially as and for the purpose herein set forth.

2. The combination of the wheeled frame having the adjustable draft-bar, the vertical screwthreaded rod journaled transversely adjustably in the said frame, the clip having female-threaded eyes mounted upon said screw-threaded rod and having a lateral oifset or recess, a link connected to the latter and having a set-screw extending through its outer end, a clevis mounted in the said link and pressed by the said set-screw, perforated brackets at the front end of the plow-beam, and a bolt connecting said brackets with the clevis-connected to the vertically-adjustable clip, substantially as and for the purpose set forth.

3. The combination,with the wheeled frame having the adjustable draft-bar and the laterally-adj ustable vertical screw-threaded rod, of the nut mounted upon the latter and having longitudinal arms notched at their outer ends, and the plow-beam having eyes provided with links adapted to be hooked in the said notches, substantially as and for the purpose herein set forth.

4. The combinatiolnwith the wheeled frame having the adjustable draft-bar, and the laterally-adjustable vertical screw-threaded rod provided with a crank at its upper end, of the clip having female-threaded eyes mounted upon the screw-threaded rod and having a lateral offset or recess, alink connected to the latterand having a set-screw pressing against a clevis extending through said link and connected by a bolt with perforated brackets at the front end of the plow-beam, a nut mounted upon the screw-threaded rod above the clip and having longitudinally-notched arms, the links connected to the plow-beam and hooked oversaid notched arms, and a clevisand chain connecting the plow-beam with the rear end of the draft-bar, substantially as and for the purpose herein set forth.`

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

FRANK SCHULZ.
